not many people seem to know the roundabout rules, even some cops, i have had some near misses out here on the redcliffe peninsula, there are usually two lanes coming into and sometimes only one lane exiting it, there are arrows indicating left turn only into roundabout in the left lane and straight through or right turrn out from the right lane, there are no lanes marked on the roundabout, on numerous occasions the car to the left of me which should only be turning left goes straight through along side me and we both try to claim the one lane out the other side and i'm sorry to say its mostly elderly drivers, maybe they don't see the road markings
